title: [Analysis of postoperative complication and its preventive measure of cervical open-door expansive laminoplasty with lateral mass screw fixation].
abstract: OBJECTIVE
  To explore the postoperative complication and its preventive measure of cervical open-door expansive laminoplasty with lateral mass screw fixation in treating cervical canal stenosis.
  
  
  METHODS
  From February 2008 to July 2011, 33 patients with cervical canal stenosis underwent cervical open-door expansive laminoplasty with lateral mass screw fixation. JOA score was used to evaluate clinical effects before and after operation. Of them, complications occurred in 6 cases, male in 2 cases and female in 4 cases. The reason of complications were analyzed.
  
  
  RESULTS
  All the patients were followed up from 6 months to 2 years with an average of 10.3 months. The improvement rate of JOA was 78.8% and incidence rate of complication was 18.2% (6 cases). There were 2 cases of axiality symptoms, 1 case of lateral mass screw pulled-out, 2 cases of cerebrospinal fluid leakage with wound dehiscence, 1 case of nerve root parlysis. These complications correlated with operative design, manipulation,improved degree of cervical curvature,postoperative management and cooperation of patient.
  
  
  CONCLUSIONS
  As an effective treatment, cervical open-door expansive laminoplasty with lateral mass screw fixation has lower incidence of axiality pain. Preoperative examination ,postoperative management ,meticulous surgical skill are very important to avoid complications.
